CORN-PLANTER.

Specification of Letters Patent.

Patented Sept. 26, 1905.

Application filed November 1, 1904. Serial No. 230,962.

To aZZ whom, it may concern:

Be it known that I, CLYDE W. MoOABn, a citizen of the United States, residing at Antwerp, in the county of Paulding and State of Ohio, have invented new andusefulImprovements in Corn-Planters, of which the following is a specification.

My invention relates to improvements in planters of that class or kind especially adapted for dropping seeds at determined distances apart, particularly for depositing corn; and the primary object is to providea machine of the kind named and for the purposes intended which is of simplified construction, efficient in operation, and durable in use.

Further objects of the invention are, first, to provide a novel form of marking apparatus which is normally out of operation and which can be thrown into operation at any time and which is designed to carry any kind of marking material, such as fertilizer, and, second, to provide amarking apparatus which may be used as a fertilizer-distributer.

A further object of the invention is to provide a planter with a movable frame whereby the seed-droppers and marking apparatus may be brought into alinementwith markings at each end of the row.

*ith these objects in view the invention consists in the novel construction of parts and their aggroupment in operative combination, as will be hereinafter fully specified and then the novelty asserted particularly pointed out and distinctly claimed.

1 have fully and clearly illustrated the improvements in the annexed drawings, to be taken as a part of this specification, and reference being thereto had Figure l is a top plan view of the complete machine. Fig. 2 is a longitudinal section on the line 2 2 of Fig. 1. Fig. 3 is a longitudinal vertical section on the line 3 3 of Fig. 1. Fig. isa central verticalsection through one of the hoppers and indicating the means for operating the feed-slides. This view is taken on the line 4 4 of Fig. l, and Fig. 5 is a vertical central section through the drivingsprocket mounted on the axle and showing the means for holding the sprocket fast to the axle.

In the drawings the same parts appearing in difierent illustrations are designated by similar reference notations, and reference being made to the drawings, A A designate the ground or driving wheels, the hubs of which are made fast to an axle 1. On the axle are arranged oppositely-placed bearings 2, one only being shown, which carry and are secured to the rear portion of a rectangular frame B, composed of side bars 3 L and end bars 5. The side bars 3 4 are provided with longitudinal slots 6, alining with each other, wherein the supporting-stirrups of a transversely-disposed frame O are hung, as hereinafter specified.

The tongue 7 is positioned and secured longitudinally in the middle of the frame B and extends rearward, as shown, and has its rear end firmly connected to the side rail 3 by a bar 8. To the, under side of the tongue is fixed a keeper-bar 9, which supports the transversely-disposed frame and prevents it from swinging down on the stirrups.

O designates a rectangular frame composed of side rails 10 11 and end pieces 12, the frame being disposed at right angles to the frame B, as shown in Fig. 1 of the drawings, and is supported by stirrups or clips 13, slidably hung in the slots 6 of the side rails of the frame B. The frame C is held against swinging downward by the keeper-bar 9, on which it rests at its middle, to bring the seed-spouts and marking apparatus into alinement with the markings at the ends of each row, whereby the movements of the whole machine to accomplish this is obviated. By mounting the frame for sliding movement said frame may be properly adjusted. To accomplish the adjustment of the frame (1, a link or arm 14 has one end pivotally connected to the side bar 10 of the frame O and has its other end pivotally connected to the lower end of the lever 15, fulcrumed to a hanger or bracket 16, secured to the rear portion of the tongue. To hold the lever 15 in adjusted position, it is provided with a suitable hand-pawl 17, the end of which engages in a sector-rack 18, secured to the rear part of the tongue, substantially as seen in the drawings. The frame O supports the members making up the seed-dropping and the marking-can devices and also supports the mechanism for operating those devices.

On the axle l is loosely mounted a driving sprocket-gear 19, made to turn with the axle by means of afixed radial arm 20 projecting from the axle and provided with an aperture in its free end, wherein is detachably inserted a pin 21, which engages in pin-holes 22, made in the body of the driving sprocket-gear. The connection of the pin with the sprocket is made by pushing the sprocket onto the pin,

IIO

where it is held engaged by frictional contact. In suitable hangers 23, secured to and depending from the ends of the frame U, is journaled a rock-bar shaft EZeL. Adjacent to each end of the rock-bar 2st is loosely mounted thereon a clutch member 25, provided with an upwardly-extending arm .26, provided at its upper end with a slot 27, for the purpose hereinafter stated. The other member 28 of the clutch is slidably mounted on the rock-bar and is thrown in and out of engagement with the members .25 by means of elbow-levers 29, fulcrumed to the frame-bar 10, as seen at 30, and their long arms carried parallel with the frame-bar 10 and at their free ends have pivot-- ally secured thereto sliding rods31,mounted in brackets 33, carried by a bar36, secured to the rails of theframe (J. The rods 31are provided with foot-plates 34, and to position the footplate of the rod 32 out of the way of the chain 41 said rod is bent laterally, as at 35. The clutches serve to control the operation of the marking can slides and are brought into engagement only when required to move the slides to discharge the markingmate rial from thecans, particularly for a distance at the ends of the'rows, and then they are thrown out of engagement with the slides in closed position and so remain until brought into action again by the rengagement of the clutches. Springs are positioned between the advance brackets 33 and collars 35, rigidly secured, and serve to normally retain the clutches out of operative position, and said clutches are adjusted to be brought into operative position by a forward pressure brought to bear upon the foot-plates 34. To permit the clutch members 28 to rock with the rock-bar, the short arms of the clutchlevers are provided with suitable slots 28*, in

which the pins in the slidable clutch members loosely engage, as indicated in the drawings.

37 designates a double inclined or arched bar having its ends supported onand secured to the rails 1O 11 and at its apex is provided with a bearing 38, wherein is journaled a studshaft 39, whereon is mounted a sprocketwheel 40, carrying a sprocket-chain 41. extending from the driving-sprocket19. The sprocket-wheel 4:0 is provided with laterallyextending pins 42, which engage against a vertically-extending arm as, fixed in the rock-bar 24 in the path of the pins 4:2. It will be seen that this tripping mechanism eventuates in rocking the rock-bar, and at each engagement of the contacting parts the bar is rocked, and through its connections hereinafter described the seed and marking devices are thus operated.

4A designates the oppositely-d isposed marking-cans of duplicate construction made in such capacity as will fit them for the purposes desired and consisting of cylindrical bodies and funnel-shaped bottoms opening into a discharge-tube 45. In the base of each of the marking-cans is made a slideway or slot wherein is disposed a sliding plate at, the outer end of which is pivotally connected to the upper end of the arm 26 by a pin at? projected through the slot 27. To the slide 46 at a lower parallel plane is a second slide-plate 48, arranged through a slideway provided in the stem of the holding-can, substantially as seen in Fig. at of the drawings. In the slides t6 and 48 are made apertures 49 50, so positioned that when the aperture 49 is opened the aperture 50 is moved from the bore of the stem and the bore is closed by the plate 48, and when the plate $6 is moved to bring the aperture e9in registration with the bore of the stem the aperture 50 will register with the bore of the stem, and the plate 4L6 will close the stem above it, as seen in Fig. a of the drawings. It will thus be seen that the space between the plate or slides measures the quantity of material which isdischarged from the holding cans at one time. As heretofore stated, the engagement of the clutch members operates these slides.

51 designates the seed-hoppers made in the usual tapering form and of such capacity as may be required to suit the machine to the uses of its work. In the bottom of the seedhoppers are made apertures, which are intermittingly opened and closed by an apertured disk 52, formed with perimetral projections or teeth 53. The disk is pivotally disposed on a support positioned in the bottom of the seed-hopper, as indicated in Fig. 1 of the drawings. Below the seed-hopper is arranged a seed-spout 54, having its lower end suitably secured in the heel of the row or furrowopeners 55 in-any suitable manner. The furrowopeners are of the usual shape, substantially as seen in the drawings, and have the upper ends of the runners pivotally fastened to the side bar or rail 11 of the frame C, as shown at 56 in Figs. 1 and 3.

On the rock-bar 24 are formed or secured upwardly-extending arms 57, having slothearings in their upper ends, in which the outer ends of reciprocable bars 58, which are projected through the wall of the seedhoppers are so arranged that their free ends engage against the projections of the disks 52, to which the reciprocations of the bars 58 give an intermittentrotation.

In order to adjust the tension of the chain 41, a stud-shaft 59 is fixed in the bar of the lever 15, and mounted thereon is a sleeve or pulley 59, on which the chain rides. It will be seen that when the lever is operated to move the frame 0 the pulley 59 automatically adjusts the tension of the chain to the adjusted position to which the frame may be moved.

A spring 60, having one end secured to the side rail 11 of the frame U and the other end fastened to the trip-arm 43, serves to hold the trip-arm in proper position against the action of the pins in the sprocket-wheel a0, as indicated in Fig. 2 of the drawings.

A suitable seat 61 is supported at the rear end of the frame B. The functions of the several elements and coacting members have been specified in the description; but the general operation of the machine may be rehearsed as follows: The driving-sprocket is made fast to the axle, which, through the medium of the chain, communicates rotation to the sprocket-wheel 40, bringing the pins therein into sequential contact with the triparm 4E3 of the rack-bar 24, causing that element to rock in its bearings, which movement reciprocates the bars 58 and intermittently rotates the seed-disks 52, and thus discharge the seeds into the furrows made by the furrow-openers. The marking apparatus is used upon nearing the end of a row, and it is controlled by the operator in the manner hereinbefore pointed out, and as each clutch mechanism may be operated independently either one or both of the marking devices may be thrown into operation at the Will of the operator. It is apparent that the marking apparatus may be used to distribute fertilizer as well as to distribute a marking material.
